7 Claims.

This invention relates to gates for prisons, and an object of the invention is to provide a gate which will prevent prison deliveries by overpowering ofthe gate keepers.

A further object of the invention is to provide a gate of such a construction as can withstand battering rams or the like forced thereagainst from either side ofthe gate.

A still further object of the invention is to provide a prison gate which will serve to house the keeper of the gate. Y

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a vertical sectional view illustrating the invention with the gate in closed position.

Figures 2 and 3 are sectional views taken substantially in the lines 2-2 and 3--3 respectively of Figure 1.

Figure 4 is a detail elevational view showing the latch means for the gate.

Figure 5 is a detail sectional View through the gearing forming part of the manual means for moving the gate from closed to open position and Vice versa.

Figure 6 is a perspective view of an operating rod and associated parts for the latch structure shown in Figure 4.

Referring to the drawings by reference numerals, let I0 indicate generally a passageway or corridor into which opens one or more entrances or exits II provided in a wall I2.

In accordance with the present invention there is located at the side of the corridor I'opposite to the wall I2 and in substantial alinement with the opening II a structure I3 which may vbe termed a blind room and which accommodates the gate I4 when the latter is in open position.

The gate I4 is constructed of steel or other suitable material, and is of somewhat shell-like form being adapted to house therein the guard or keeper of the gate. V

The side walls of the gate I4 are provided with tracks I5 that engage anti-friction rollers I6 suitably journaled in opposing side walls of the room I3.

Adjacent its forward end, that is, adjacent the end Illa thereof, the gate I4 is mounted on suitable rollers I'I while adjacent the rear end, that is the end I4b thereof, the gate hassuitably journaled in bearings I8 depending from the floor or bottom thereof a transverse shaft I9 on the ends of which are cog wheels 20. The cog wheels 20 are in mesh with rack bars 2| laid on the floor ofthe room I3. f

The shaft I9 may, if desired, be driven from a suitable electric motor 23 suitably arrangedY in the gate I4 and connected with the shaft I9 through belt and pulley or chain and sprocket means, or any other suitable power transmittingmeansv 24. Y

Also, and as clearly shown in the drawings, the movement of the gate from open or'closed position may be controlled directly and manually by the guard through the medium of a shaft 25 arranged within the gate and in driving engagement with the shaft I9 through the medium of bevel gearing 2B. At its upper end the shaft 25 terminates Within a gear case 21 suitably mounted internally and on one side wall of the gate I4, and within the gear case 2l the shaft 25 is in engagement with a suitably mounted Vstub shaft 28 through the medium of bevel gearing 2,9. On its outer end the stub shaft 28 is squared to accommodate an operating handle 30.

Entrance to the gate lI4 is had at the end |40. thereof through the medium of a hollow hinge door 3| provided internally with upper and lower latches or locks 32 simultaneously controlled through a suitable handle 33 connected with the latch members inany suitable manner.

Access to and from the blind room I3 may be had through the gate I4 from theV end I 4b of the gate, which end, as clearlyshown in the drawings, is provided with a suitable hinge door` 34.

Bumpers 35 are provided on the inner end wall ofthe chamber or room I3. 1';

For locking the gateY I4 in its closed or projected position, which is the position shown in Figure 2,V there are provided at theY end I4b of the gate spring projected latch, or locking devices 36 the bolts of which are engageable with keepers 31 suitably mounted on theside Walls of the room I3 as also shown in VFigure 2. The bolts of the latches 36 are connected for simul-V taneous Voperation through the medium vof links 38 connected with a plate 39 onmone end ,of Ya stub shaft journaled in thefend wall -I4b of the gate. rI'he stub shaft supporting the plate 39 at its inner end is provided with a crank arm or in any other suitable manner for connection with one end of a link 4I, that in turn is connected to one end of a suitably mounted bell crank 42. Connected to the other end of the bell crank 42 is an operating lever 43 that slides or operates in suitable guides 44 provided therefor internally of the gate. l

For Ventilating purposes there is provided in the top or roof of the gate adjacent the inner end thereof a ventilator Y45, while for communi- Ycation with those on the outside, there is provided for the convenience of the guard within the gate a suitablespeaking tube 46. 1

In the side wallsjof thergate adjacent the top thereof are suitable Windows 41. Also provided in the sidewalls of the gate'are ports 48 for f accommodatingthecbarrels ofgunseortsuitable fire arms'. Y Y

From the above it will be apparent that when the gate is in the closed position, that is, with its forward end Ma in abutting engagement with the wall l2 the corridori!) as well as the passageway or opening Il are closed. thereby. When the guard or keeper within the gate through the mechanism provided'for that pur-1 pose causes'the gate to be moved to an opening position, that is, into a positionY within. the.
